In the 1980s, scientists captured the precise mechanics of a protein machine. It looked strange, to researchers its tall thin structure with stubby legs invoked the enchanted broomstick that stole the show in "The Sorcerer's Apprentice" segment of Disney's 1940 Fantasia film.
It is common in some fields to infer that differences in one area will ultimately reflect differences in the end product. Though the real abuse and misuse is with neuroscience and tools like fMRI imaging, they are not alone.
Geneticists have also commonly suggested that RNA differences will mean differences in proteins but the majority of RNA expression differences between individuals have no connection to the abundance of a corresponding protein, finds a new study.
Instead, there is likely a yet-unidentified cellular mechanism that regulates gene expression and RNA measurements to characterize gene function won't stand alone.
If you can't balance on one leg for 20 seconds you are more likely to have small blood vessel damage in the brain and reduced cognitive function, even if you otherwise seem healthy, according to new research in Stroke.
The study consisted of 841 women and 546 men, average age of 67. To measure one-leg standing time, participants stood with their eyes open and raised one leg. The maximum time for keeping the leg raised was 60 seconds. Participants performed this examination twice and the better of the two times was used in the study analysis. Cerebral small vessel disease was evaluated using brain magnetic resonance imaging.
Though the U.S. government is touting claims that it has created an economic engine better than at any time in the 20th century, the reality is much different and a large part of the reason why Congress has lurched to the opposition party of U.S. President Barack Obama.
If people have been unemployed for so long they can no longer get unemployment benefits, the government frames it as that they went back to work. And we have been engaged in a culture war on business, everything from nuclear energy and natural gas to manufacturing of every kind.
You should not be surprised by the irregularity of a newborn infant's sleep patterns but by the age of six months, if the baby is not sleeping through the night, many parents wonder if something is wrong with their baby or their sleeping arrangements.
It helps parents to understand that "normal" sleep patterns for a child are somewhat broad, according to a new paper.
Researchers at the University of Guanajuato (UGTO), in middle Mexico, developed an extraction column which recovers metals companies use in their production processes; and thus avoid environmental pollution and lessen economic losses.Using the principles of liquid-liquid technology, researchers have developed an extraction column which recovers metals companies use in their production processes and avoids both environmental pollution and lessen economic losses. The technology is already at laboratory prototype stage and the creators are in the process of obtaining a patent. Credit: University of Guanajuato/Investigación y Desarrollo
Neutrophils are a type of white blood cell and are summoned to fight infections or injury in any tissue or organ in the body, regardless of cellular and biochemical composition.
How do neutrophils, the body's all terrain vehicles, move in these confined spaces?
A team from Brown University's School of Engineering and the Department of Surgery in the Warren Alpert Medical School collaborated find out. Their technique involved two hydrogel sacks sandwiched together with a minuscule space in between. Neutrophils could be placed in that space, mimicking the confinement they experience within tissue. Time-lapse cameras measure how fast the cells move, and traction force microscopes determine the forces the cells exert on the surrounding gel.
How people behave in a social network is somewhat mysterious, in the same way we can predict a presidential election with unprecedented accuracy but we can't predict how one person among the six percent of America that chooses a president will vote.
Decision-making often involves a confluence of opinions, decisions and behaviors of individuals influenced by their online networks, the same way they used to be shaped by their real-life networks.
A recent project set out to apply some math to help find some answers.

In some cases, seniors begin to show memory decline and cloudy judgment and researchers have correlated that to lost and altered connections between neurons in the brain.
A new study finds that riluzole, currently on the market as a treatment for Lou Gehrig's Disease (Amyotrophic lateral sclerosis - ALS) may help prevent these changes. The team found they could stop normal, age-related memory loss in rats by treating them with riluzole. This treatment, they found, prompted changes known to improve connections, and as a result, communication, between certain neurons within the brain's hippocampus.
Modern human skeletons, with our lightly-built form, evolved only relatively recently, after the start of the Holocene about 12,000 years ago and even more recently in some human populations, according to a study that used high-resolution imaging of bone joints from modern humans and chimpanzees as well as from fossils of extinct human species.
For millions of years, extinct human predecessors had high bone density. A higher decrease in the density of lower limbs than in that of the upper limbs suggests that the transformation may be linked to humans' shift from a foraging lifestyle to a sedentary agricultural one.
No one in business can figure out what an 'SEO expert' is - in most cases it is simply the person who knows the password to the Facebook account. A new study finds that it may be better to have less popular people rather than marketing experts talking about your fundraising efforts, because people with fewer friends on Facebook raise more money for charity than those with lots of connections.
Professor Kimberley Scharf, economist at the University of Warwick, analyzed data from JustGiving.com and found a negative correlation between the size of a group and the amount of money given by each donor - with the average contribution by each person dropping by two pence for every extra connection someone had on Facebook.
Previous studies of hair loss have identified signals from the skin that help prompt new phases of hair growth and a new study reveals a new way to spur hair growth.
Today is the day when a whole lot of people will be exchanging gifts that don't fit or they don't want, and maybe buying something they did want.
It's the perfect time to think about gift exchanges. Gift exchanges can reveal how people think about others, what they value and enjoy, and how they build and maintain relationships. Researchers are exploring various aspects of gift-giving and receiving, such as how givers choose gifts, how gifts are used by recipients, and how gifts impact the relationship between givers and receivers.
